Questions to Ask a Nephrologist
Questions for an appointment with a kidney specialist, covering what your test numbers mean, which medicines may need adjusting, how often you will be monitored, and when dialysis or transplant planning begins. Written for patients seeing a nephrologist for the first time or managing chronic kidney disease over years.

The questions
Open any question to see why it works.
- 1
What stage is my kidney disease, and what is my eGFR today?
Staging is what determines how often you are seen and which medicines become unsafe, so it is the anchor for everything else in the visit. If the answer is only qualitative, ask for the number and the date it was drawn.
- 2
How much has my kidney function changed over the past year?
A single result says less than the slope. Someone stable at a reduced level and someone falling steadily can share the same eGFR and need very different plans, so ask for the trend rather than the latest value.
- 3
What caused the damage, and is that cause still active?
The answer separates a one-off injury from something ongoing such as uncontrolled blood pressure, diabetes, or an autoimmune process. If the cause is still active, treatment aims at that first, and the honest answer is sometimes that the cause is not known.
- 4
Which of my current medications need a dose change because of my kidney function?
Many drugs are cleared by the kidneys and are dosed on the assumption of normal clearance. This is the question most likely to change something the same day, so bring the actual bottles rather than a remembered list.
- 5
Are there any medicines or supplements I should stop taking, including over-the-counter ones?
Patients rarely mention ibuprofen, herbal products, or protein powders because they do not think of them as medication. Naming the categories out loud is what surfaces them.
- 6
What blood pressure number are we aiming for, and how do we get there?
Blood pressure control is usually the main lever available to slow decline, and targets differ by person. A specific number lets you judge your home readings instead of guessing whether they are acceptable.
- 7
What blood and urine tests will you run from now on, and how often?
Knowing the schedule tells you when to book labs and lets you notice if a round gets missed. Ask whether urine protein is included, since blood tests alone can miss changes in the kidney's filtering.
- 8
What results would make you change my treatment plan?
This turns monitoring from a ritual into something you can read. It also tells you what your specialist is actually watching, which is often narrower than the whole panel you receive.
- 9
Which symptoms should make me call your office rather than wait for the next visit?
Kidney disease can advance without symptoms, so the useful information is the short list that counts as urgent: swelling, sharply reduced urine output, breathlessness, confusion. Vague reassurance to call anytime leaves you deciding alone at 2am.
- 10
Can you refer me to a renal dietitian?
Kidney diets are specific and shift with your stage and lab results, which is more detail than a specialist visit can cover. A referral is also usually the route to advice that accounts for your other conditions.
- 11
How much sodium, potassium, phosphorus and protein should I be aiming for each day?
General advice to eat healthily can be wrong here, since foods often recommended elsewhere are high in potassium or phosphorus. Numbers, even approximate ones, let you read a label and decide.
- 12
How much fluid should I drink a day, and should I be writing it down?
Advice on fluid varies with your stage and whether you retain fluid, so drinking more is not automatically better. Ask whether daily weight is a more useful thing to track than volume.
- 13
Can I keep exercising the way I do now, or is anything off limits?
Most people are told to stay active, so the value is in the exceptions relevant to you, such as contact sport with a single functioning kidney or heavy exertion in heat while on diuretics.
- 14
How does my kidney disease interact with my other conditions, and who coordinates that care?
Diabetes, heart failure and kidney disease pull treatment in different directions, and the person deciding trade-offs should be named. Without an answer, conflicting instructions from different clinics land on you to reconcile.
- 15
If my function keeps declining, at what point would we start planning for dialysis or a transplant?
Preparation takes months: access surgery, evaluation, insurance. Asking early means the threshold is set in advance rather than under pressure, and knowing you are far from it is also useful.
- 16
What would hemodialysis and peritoneal dialysis each mean for my week?
The clinical comparison is less decisive for most people than the practical one: travel to a center several times a week against nightly exchanges at home. Ask what each would require of your household and your job.
- 17
Am I a candidate for a transplant, and when should I be referred for evaluation?
Eligibility depends on factors beyond the kidneys, and evaluation can begin before dialysis. If you are not a candidate, it is better to hear why now than to assume a route that is closed.
- 18
What can I expect over the next few years if things go well, and if they do not?
Asking for both directions gets you a range rather than a reassurance, which is what you need for decisions about work, housing and family. Expect uncertainty in the answer; a specialist who gives a precise date is overstating.
- 19
What will treatment cost me, and is there someone here who helps with coverage?
Dialysis, transplant medication and frequent labs carry costs that arrive before anyone mentions them. Most kidney programs have a social worker or financial counselor, and asking for that person by role is faster than asking your specialist for figures.
- 20
Who do I contact between visits, and how long does a reply usually take?
Knowing whether messages go to a nurse line, a portal, or the office switchboard, and the realistic turnaround, decides whether you wait or go to urgent care when something changes.
Getting the most from a nephrology appointment
Practical guidance for the conversation itself.
Before you go in
Before you go in
- 1Book your labs far enough ahead that the results are back before the appointment, otherwise half the visit becomes guesswork.
- 2Bring the actual containers for everything you take, prescriptions, painkillers, vitamins and herbal products included.
- 3Pull your last few creatinine and eGFR results from the patient portal and write them in order with dates, so you can ask about the trend.
- 4Take your blood pressure at home for a week beforehand at the same time of day and bring the readings.
- 5Write your three main questions at the top of one page. Appointments are short and the list you keep in your head shrinks under pressure.
Reading your own results
Reading your own results
eGFR is an estimate, not a measurement
It is calculated from creatinine, which moves with hydration, recent illness and muscle mass. One lower reading is not the same as decline, which is why the sequence of results matters more than any single one.
Urine tells you something blood does not
Protein or albumin in the urine can change before eGFR does. If your visits only cover blood work, ask whether a urine albumin-to-creatinine ratio is part of your monitoring.
Ask what would count as a change
Rather than tracking every value, ask which two or three numbers your specialist watches and what movement in them would prompt a call. That gives you something to look for when results appear in the portal.
If dialysis or transplant comes up
If dialysis or transplant comes up
Ask about timelines, not just options
Vascular access, transplant evaluation and insurance approval each take time. The useful question is what needs to start now to keep both routes open later.
Bring the person who shares your week
The choice between in-center and home treatment affects a household schedule, not just a patient. Whoever would drive you or help with exchanges should hear the explanation directly.
Ask what happens if you choose neither
Conservative management is a real option that is discussed less often. If you want to understand it, you will usually have to raise it yourself, and it is a reasonable thing to ask about without committing to anything.
What goes wrong
What goes wrong
- Feeling well is not evidence of stability. Function can fall a long way before symptoms appear, which is why labs continue even during good stretches.
- Stopping or halving a medicine without telling anyone. Blood pressure and diabetes drugs are the ones most often quietly abandoned, and both matter here.
- Assuming another doctor has passed on the plan. Ask for the visit summary and take it to your other appointments yourself.
- Leaving without knowing the next step. Before you stand up, confirm the date of your next labs, the date of your next visit, and anything that changed today.
